# init(origin:direction:allowing:alignment:)

Creates a new raycast query.

## Declaration

```swift
init(origin: simd_float3, direction: simd_float3, allowing target: ARRaycastQuery.Target, alignment: ARRaycastQuery.TargetAlignment)
```

## Parameters

- `origin`: A 3D position that describes the raycast’s starting point.
- `direction`: A 3D vector that describes the raycast’s direction.
- `target`: The type of plane with which you allow the raycast to intersect.
- `alignment`: The target’s alignment with respect to gravity with which you allow the raycast to intersect.

## Discussion

Discussion This creates a query by supplying a 3D starting place and vector. To acquire a raycast query using a screen point and vector that points outward from the user, call raycastQuery(from:allowing:alignment:) on ARSCNView.
